Convert STP to GLB Online
Convert STP to GLB in seconds. STP (STEP) is the 3-letter extension for the STEP CAD standard; GLB's strength is this: a single efficient file bundling geometry, materials, and textures. No software installation required — everything runs in your browser.

Why Convert STP to GLB?
If you need a file built for fast-loading real-time delivery for web and AR viewers but only have one built for exact engineering geometry exchange between CAD systems and manufacturers, converting is usually the fastest path — STP (STEP) and GLB serve different enough purposes that recreating the asset from scratch rarely makes sense.
Our engine reads a file built around exact engineering geometry exchange between CAD systems and manufacturers and rebuilds it aiming to preserve this: a single efficient file bundling geometry, materials, and textures — rather than producing a generic, lowest-common-denominator result.
This conversion comes up whenever you need fast-loading real-time delivery for web and AR viewers instead of exact engineering geometry exchange between CAD systems and manufacturers. STP (STEP) and GLB serve genuinely different purposes, so moving between them isn't just a formality.
How to Convert STP (STEP) to GLB
- Upload your STP file.
- MiConvert converts it to GLB, aiming to preserve what makes GLB useful: a single efficient file bundling geometry, materials, and textures.
- Download the converted GLB file.
- Use it directly with Three.js, Babylon.js, iOS/Android AR viewers.
Key Conversion Features
- Fast turnaround, typically under a minute per file
- Built to handle the real-world quirks of files meant for exact engineering geometry exchange between CAD systems and manufacturers, not just a textbook version of the format
- No local software installation required for either side — not SolidWorks, Fusion 360, Inventor, CATIA, not Three.js, Babylon.js, iOS/Android AR viewers — everything runs in the cloud
- Understands that STP is the 3-letter extension for the STEP CAD standard and GLB is the compact binary form of glTF, rather than treating the conversion as a blind format swap
- Purpose-built for the shift from exact engineering geometry exchange between CAD systems and manufacturers to fast-loading real-time delivery for web and AR viewers, not a generic pass-through

Frequently Asked Questions
Do I need any special settings before uploading my STP file?
No special setup is required — upload the file as-is. STP (STEP) files meant for exact engineering geometry exchange between CAD systems and manufacturers convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
What happens to features specific to STP that GLB doesn't have?
STP (STEP)'s real strength — true B-rep geometry — exact surfaces and curves, not an approximation — has no equivalent once converted, since GLB's constraint is: not natively supported by many older DCC and game-engine importers.
Is the conversion from STP to GLB reliable?
Straightforward files convert reliably. STP (STEP)'s limitation — not readable by mesh-only tools like slicers without conversion — combined with GLB expecting fast-loading real-time delivery for web and AR viewers, means unusual or edge-case source files can occasionally need a second look.
What software works with the converted GLB file?
GLB is used by Three.js, Babylon.js, iOS/Android AR viewers. If you were working with SolidWorks, Fusion 360, Inventor, CATIA (which produces STP (STEP)), this conversion is the direct bridge between the two.
Do I need SolidWorks, Fusion 360, Inventor, CATIA installed to convert my file?
No — the conversion happens entirely on our servers. You don't need SolidWorks, Fusion 360, Inventor, CATIA, and you don't need Three.js, Babylon.js, iOS/Android AR viewers either unless you plan to open or edit the GLB result afterward.
